Froyo Problem

I've got a big problem with my phone. Just got the update to 2.2 and when it booted back up it asked if I wanted to use the default or Helix 2 as my home screen. I chose Helix and told it to make it my default. Well now, I'm getting an error with Helix and it will not stop bringing up the Force Close or Report error screen. If I hit FC, it just comes up again. I can not get to my settings or anything. I even tried taking out the battery hoping it would help. Any suggestions PLEASE????
